IDC reports that IBM achieved worldwide server factory revenue growth of 66.1% year-over-year in the first quarter of 2015 in $250K+ servers. According to IDC, IBM achieved industry-leading 63.6% revenue share in $250K+ servers in the quarter, with z Systems growing 118% year-to-year. IBM's leadership position in the $250K+ server share is evidence of continued momentum for the z Systems.

The report builds on IBM's introduction of the z13 in January 2015, a mainframe built for the digital economy. With the ability to handle 2.5 billion transactions a day, the z13 is designed for the skyrocketing growth in mobile transactions where consumers expect to interact with businesses anywhere, anytime through smartphones and mobile devices. The z13 is the first mainframe to process transactions and perform advanced analytics simultaneously, allowing for fraud detection on every transaction.

"During the past 18 months, IBM’s server strategy has undergone a massive transformation as we deepen our investment in high value servers," said Tom Rosamilia, Senior Vice President for IBM Systems. "With the introduction of the z13 and the POWER8 processor, it is clear that we are offering clients differentiated products to handle the demands that industry disruptors like cloud, analytics, mobile, social and security put on businesses every day."
